Power Steering Pump for Man

The power steering pump is driven by the engine to convert the low-pressure oil in the oil tank into high-pressure oil and deliver it to the steering control valve.
At present, automobile steering pumps are mostly double-acting vane steering pumps, which are mainly composed of ordinary double-acting vane pumps, flow control valves and pressure safety valves;
The double-acting vane pump provides high-pressure oil. The flow control valve ensures that the steering pump outputs a flow suitable for the entire vehicle.
The pressure relief valve controls the maximum output pressure of the steering pump. For gasoline engines with low engine power, a pressure switch should also be equipped.

The working principle of power steering pump

After the drive wheel drives the rotor to rotate, the blades expand under the action of centrifugal force, and form a working cavity with the stator, rotor, and oil distribution plate.
When the rotor and blades rotate from the small arc area to the large arc area on the inner surface of the stator , The volume between the two blades increases, the pressure decreases, and the oil is sucked through the oil suction port of the oil distribution plate;
When changing from a large arc area to a small arc area, the volume between the two blades decreases and the pressure increases.
The oil is discharged through the oil discharge port of the pressure plate, and the discharged high-pressure oil enters the steering gear through the steering oil pipe to provide steering assistance.

The role of power steering pump

1. The power steering pump is the power source of the hydraulic power steering system. It uses the engine as the transmission medium to convert mechanical energy into hydraulic energy. The steering gear converts the hydraulic energy into mechanical energy through the hydraulic oil output by the oil pump, thereby reducing the driver's operation Strength, improve the maneuverability of the vehicle.
2. Control the internal pressure of the power steering pipeline through the pressure relief valve to ensure the safety of the steering system; 3. Control the flow of the steering system through the flow control valve to ensure the driver's steering feel when the vehicle is running at high speed.
